It might not work at all. +Want to help? Docs are at +ftp://beta.xfree86.org/pub/xf86/devel/Documentation/apm + +This is the Alliance Promotion driver for XFree86 4.0+. It currently only +supports the AT3D, AT25 chipsets (found on various Voodoo-Rush cards) and AT24. +There is incomplete support for the 6422. The 6422 chips are supported in the +XFree86 3.3.x series. + +What has worked on my computer : + - XAA for 8/16/24/32 bpp + - DGA and DGA2 + - DPMS + - glide2x + - using as a module + - shadow framebuffer + - AT3D + - AT24 + - AP6422 (although with problems, including locks) + - multi card setup (with and without Xinerama) + - Xv images, even with (slightly modified) glide2x ; note that there is + still a little problem with vertical offset. + +There is some support for PC-98 with the help of Isao Ohishi +(ohishi@aero.rim.or.jp). It's still under development. I hope that 8bpp +works correctly. + +What has not worked : + - I2C (I'm not sure my card, Hercules 128/3D, has proper cabling) + +What is untested : + +What should be done : + - overlays (with the video engine, everything should be overlayable + with everything) + - (why not) 3210 support + + + Loïc Grenié + +Authors: +----------------------------------------------------------------------- +Kent Hamilton Initial creation. +Henrik Harmsen Lots of additions and fixes. <hch@cd.chalmers.se> +Loic Grenie Conversion to 4.0. <grenie@lami.univ-evry.fr> + Additions and fixes. + + +History: +----------------------------------------------------------------------- +Created by Kent Hamilton for Xfree86 from source from Alliance + +Modified 1997-06 by Henrik Harmsen + - Added support for AT3D + - Acceleration added for 8,16,32bpp: (for AT3D and AT24) + - Filled rectangles + - Screen-screen bitblts + - Host-screen color expansion bitblts for text + - DPMS support + - Enabled hardware cursor code (also in 8bpp) + - Set to programmable VCLK clock + - Set MCLK to 57.3 MHz on AT3D. + - Various bugfixes and cleanups + +Modified 1997-07-06 by Henrik Harmsen + - Fixed bug that made the HW cursor screw up on VT switches + - Probably fixed bug that screwed up the screen when using + screen-screen bitblts. This forced me to put an ApmSync() at + the end of ApmSubsequentScreenToScreenCopy() which makes + me unhappy... But: Better it works than not... + +Modified 1997-10-19 by Henrik Harmsen + - HW line drawing. + - HW clipping. + - Added support for ROP's. + - Text acceleration now lots faster and support for accelerated + proportional text. (Uses SCANLINE_PAD_DWORD + clipping). + - Combined write for many register writes gives good + general speedup. (write x+y as a single 32 bit entity, rather + obvious, really...:-) + - Now waits for correct number of free slots in FIFO before + issuing writes to the card. + This seems to have eliminated the last instances of dropped + interrupts from serial IO and no more lost packets in PPP :-) + - Converted cursor support to use XAA interface. + - Fixed ApmSync(). Finally removed call to ApmSync at end of + ApmSubsequentScreenToScreenCopy() :-) + +Modified 1998-03-29 by Henrik Harmsen + - Added DGA support. + - Added accel support for AP6422. Fixed AT24 accel support. + - Fixed clock register calculation for AP6422 and AT24. + - DPMS support for AT24 & AP6422. + - 2% faster text accel for AT24/AT3D :-) + +Modified 1998-12-18 by Loic Grenie + - Converted to Xfree86 4.0 driver interface. (Only support for + AT25/AT3D chips). + +Modified 1999-03-14 by Henrik Harmsen + - Various fixes to bring it up to 3.9Pd. + - Added preliminary (completely untested) support for dynamic + loading. + +Modified 1999-07-07 by Loïc Grenié + - Converted to new RAC. Support for DGA and DGA2, I2C, Rush extension. + +Modified 2000-02-10 by Loïc Grenié + - Bug fixes + - AP6422 (bugged !) + - Xv driver |
